flintronic Brass Presta Valve Adapter, 5PCS Bike Pump Adapter-(Pack of 5 + 10 Caps), Valve Adapter for Bike Convert Presta to Schrader, Inflate Tire Using Standard Pump+Air Compressor, for all Bikes

Ordered late the night before and arrived at midday, excellent. Work perfectly, fits well and really easy to use. And a fair amount of spares for a really affordable price. Highly recommend. Be careful if you are taking off the adapter whilst the tire is under pressure. If your Presta valve is a bit loose it can unscrew it as well. I discovered that whilst trying a diy version.

USEFUL ITEM ,THANKS

Helps blow the presta valves up with a normal schrader pump ,saved my bacon when I got a flat on the road

It did the job on my sons bike , as it had a different valve than the traditional one.So,happy with it. You get plenty of spares in the box and easy to use.

It does the job

Very good

Just what I needed
